Primary primitive neuroectodermal tumor of the kidney.

Renal primitive neuroectodermal tumor (PNET) is a rare entity. It should be differentiated from other primary renal malignancies. The differentiation of the malignant small round cell tumors may be challenging; however, it is essential for better management of the patient. We report a 45-year-old male having complaints of pain in the abdomen, hematuria, and mass in the abdomen for 6 months. Abdominal and pelvic sonography finding showed cystic-solid, right renal mass suggestive of malignancy. On histopathology diagnosed as malignant small round blue cell tumor suggestive of primitive neuroectodermal tumor. On immunohistochemistry, CD99 positivity confirmed the diagnosis of primary PNET of the kidney. We are presenting this case for its rarity, clinical presentation, and pathological findings.

Primary Squamous Cell Carcinoma of Urinary Bladder - A Rare Histological Variant.

Primary squamous cell carcinoma of urinary bladder is a rare histological variant of epithelial bladder tumours. Histopathological types are associated with significant disease outcome, so it is essential to find, on microscopy the exact type of urothelial carcinoma. Herewith, we present a 70-year-old male having 3 months history of difficulty in micturition, reduced frequency of urine and associated pain. On Contrast Enhanced CT scan abdomen pelvis, showed irregular large urinary bladder mass with hydroureter and hydronephrosis. Internal iliac group of lymphnodes was enlarged. On histopathology diagnosed as pure squamous cell carcinoma of urinary bladder grade II with muscle invasion. We are presenting this case for its clinical, radiological and histopathological findings.

Effect of antioxidants and antibiotics on levels of seminal oxidative stress in leukocytospermic infertile men.

Defective sperm function is the most common cause of infertility. A prospective study was carried out to correlate the concentration of nitrite (the stable metabolite of nitric oxide) in seminal plasma with leukocytospermia, and sperm membrane integrity. Total Fifty-seven normozoospermic subjects with and without leukocytospermia visiting the Infertility clinic at KH and MRC, Karad, were included in the present study. Semen samples were checked for sperm concentration, total sperm count, sperm motility, seminal leukocyte concentration and sperm membrane integrity as Hypoosmotic Swelling Test. Similarly the concentration of nitrite in seminal plasma was measured by Griess reaction and total antioxidant power measured as ferric reducing ability of plasma. The concentration of nitrite in seminal plasma was found to be raised with significantly increased leukocyte concentration in semen. Also significantly lowered levels of total antioxidant power along with defective sperm function was observed. Our results suggest that supplementary treatment of antioxidants with antibiotic for leukocytospermic infertile male patients may improve the sperm membrane integrity.
